Antigravity Agent Manager broken on Windows; menus do nothing, missing Inbox and Playground

,

The main Antigravity editor window works, but the Agent Manager window is partially broken.

In Agent Manager:

  • clicking top menu items such as Antigravity, File, Edit, and View does nothing
  • right-click only shows “Copy”
  • the window opens, but key UI actions appear non-functional

This issue persists after:

  • clean reinstall
  • deleting local profile/config data multiple times
  • downgrading Antigravity
  • running with --disable-extensions
  • disabling antivirus
  • running as Administrator
  • testing with two separate Google accounts
  • testing on a different PC with a different user

Relevant recurring log errors include:

  • Menu item references a command antigravity.importAntigravitySettings which is not defined
  • Menu item references a command antigravity.importAntigravityExtensions which is not defined
  • Menu item references a command antigravity.prioritized.chat.open which is not defined
  • cannot decode UserSettings from JSON: “[object Object]” is not valid JSON
  • failed requests to a localhost Antigravity feature endpoint
  • Electron/Chromium SSL error: net_error -202

I also see additional extension/workbench-related errors:

  • [vscode.git]: property ‘title’ is mandatory and must be of type ‘string’ or ‘object’
  • Extension ‘ms-python.vscode-python-envs’ CANNOT USE these API proposals ‘terminalShellEnv, terminalDataWriteEvent’. You MUST start in extension development mode or use the --enable-proposed-api command line flag
  • Extension ‘ms-python.python’ appears in product.json but enables LESS API proposals than the extension wants

The issue still persists even with --disable-extensions, so these extra Git/Python errors may be secondary, but I am including them in case they are related to a broader workbench/extension integration problem.

The extension host and language server appear to start, so this looks like an Agent Manager UI / command registration issue rather than a full startup failure.

Steps to reproduce:

  1. Install Antigravity on Windows.
  2. Sign in to a Google account.
  3. Open the main Antigravity editor window.
  4. Open Agent Manager.
  5. In Agent Manager, click the top menu items such as Antigravity, File, Edit, and View.
  6. Right-click inside the Agent Manager window.

Actual result:

  • top menu items do not respond
  • right-click only shows “Copy”

Expected result:

  • top menu items should open normally
  • right-click should show the normal context menu
  • Agent Manager should be fully interactive

Note: the in-app Provide Feedback form is also stuck on “Submitting”, so I am posting here instead.

I am experiencing the exact same behavior. The Agent Manager window is completely unusable.

Same on MacOs (Tahoe 26.4.1)

There is a fix in another post, just turn off themes you use. Worked for me

I do not have any theme extensions, no custom extensions whatsoever. Only the shipped default ones. It is a bright new installation. But even disabling all of them does not help.

Having the same issue. No themes installed. Tried a new install. Also tried disabling the themes it shipped with. Any solution?

same issue. Had a lot of horrible lock ups too and forced hard resets required recently (Win 11, i9 13900k) updates not working and now fresh install Agent manager menu still not working. No theme installed as far as I know.

I’m having the same issue. Not sure if it helps, but I have the following errors in the renderer.log file:

[error] [google.antigravity]: Menu item references a command `antigravity.importAntigravitySettings` which is not defined in the ‘commands’ section.

[error] [google.antigravity]: Menu item references a command `antigravity.importAntigravityExtensions` which is not defined in the ‘commands’ section.

[error] [google.antigravity]: Menu item references a command `antigravity.prioritized.chat.open` which is not defined in the ‘commands’ section.

According to Gemini:

What this means: The user interface is trying to render options for the File, Edit, and View menus based on its configuration, but the underlying commands that those menu items are supposed to trigger haven’t been properly defined or registered by the google.antigravity extension. When the application engine (which is built on top of VS Code’s core) encounters menu items linked to missing commands, it often fails to render the dropdown menus entirely, or it renders empty/unclickable buttons.

Next Steps: Because these errors are coming from the core Antigravity extension’s configuration (package.json missing command definitions), this is a bug with the current build of the Agent Manager itself rather than a misconfiguration on your local machine. You may need to wait for an update to the Antigravity Agent Manager that fixes these missing command references, or roll back to a previous version if this just started happening after an update.

I’m not sure when it broke. I was using 1.19.6 and it worked fine but today I got a message that the current version of the agent manager is no longer supported and forced me to upgrade.

I ended up solving it by completely switching to Linux but, that’s not convenient for some people.
